One of the most commonly used means of the city’s electric traffic system is trolleybus that has a lot of advantages in comparison with fixed-route taxis, buses and trams. During trolleybuses operation, the most electric and mechanical load has an effect on the traction electric engines, on which the further effective operation of a trolleybus on a transfer line depends. Statistic data concerning the trolleybuses operations in Ukraine prove that reliability of traction electric engines has been reduced for subjective and objective reasons over the past 10-15 years. New developments and the use of technologies are therefore needed for more effective use of the known technical equipment, its modernization, reliability improvement and extending the service life. To determine the effectiveness of trolleybus operation on the route, the modern methods of reliability assessment of the traction electric engines are used, which allow to get adequate characteristics of the structure, functional links of parts and units. But some methods don’t meet the necessary requirements to ensure the reliability of traction electric engines operation. So the subject and the tasks of the research work are still relevant today. New solutions of characterization the reliability of traction electric engines guarantee reducing energy and resource consumption during operation, repair and production. A methodology is presented that allows assessing the operational reliability of electrical machines from the point of view of system analysis. Uncertainty of information data arising during the operation of electrical machines is considered. The decomposition of the goal for the efficient operation and maintenance of electrical machines has been carried out, which is reflected in the form of a "goal tree". The results obtained can be used as initial data for the formulation and solution of a number of problems of control over the operational reliability of electrical machines.

“…With the development of the electronic system of special vehicle platforms, many types of special vehicles have been equipped with an increasing number of electronic devices, monitoring instruments, and the total amount of exchanging data, sharing information and processing information between these devices and instruments, which puts forward higher-level requirements for the special vehicle data bus. 1 At present, the most common special vehicle platforms adopt three communication networks: the RS422 bus, the controller area network (CAN) bus, and the Ethernet. 2 The advantage is the high reliability, but the disadvantage is the diversified interface, for it is difficult to achieve networking without a unified interface.…”

. Optical fiber bus technology is an important research direction in communication systems of electronic devices in special vehicle platforms. According to the requirements for communication quality between devices in special vehicle platforms, an optical fiber bus based on gigabit passive optical network topology is proposed. A data cache-based predictive weighted interpolated polling dynamic bandwidth allocation method is presented and investigated for the optical fiber bus’s upstream bandwidth allocation. The network controller establishes a weighted buffer area for the communication requirements in the polling period according to the type and data volume of the network terminal (NT) data stream and dynamically allocates the bandwidth of each optical NT to better meet the communication requirements for different data within the special device platform. Verification is done by means of OPNET software simulation and the establishment of a NT simulation test system in the laboratory. This proves that the proposed dynamic bandwidth allocation algorithm can reduce the end-to-end delay of RS422 port data by more than 50% and meet the Ethernet and controller area network port data delay requirements.
